老字号企业动态能力的构建过程——烙印视角的案例研究

本文运用单案例研究方法,聚焦拥有百年历史的中国白酒老字号企业,基于烙印视角,探究老字号企业动态能力的构建过程。研究发现:(1)适度稳定的非敏感期和高度动荡的敏感期,分别促使创始烙印维持和新烙印源出现,由此构成动态能力构建的前提条件;(2)老字号企业通过破坏性重组和适应性创新两种机制,构建烙印还原能力和烙印构造能力。本文结论丰富了烙印和动态能力的关系研究,揭示了烙印视角下动态能力的过程“黑箱”,为企业兼顾烙印的新颖性和稳定性提供理论启示和案例借鉴。     

复合模板剂合成SBA-15介孔分子筛的结构表征及机理研究

采用复合模板剂P123及Tritonx-100合成新型SBA-15介孔分子筛,分别利用N2等温吸附、X射线衍射及透射电镜对样品进行表征。介孔分子筛比表面积可达600 m2/g,单位质量的孔容积大于1 mL/g,平均孔径为7~8 nm,孔径分布窄,孔道长程有序,结晶度较高。通过与单一模板剂合成样品的比较可知,辅助模板剂Tritonx-100能有效地改善孔径分布及孔道排列,通过实验找出了最佳模板剂配比为n(Tritonx-100)∶n(P123)=4∶1。     

The impact of socialist imprinting and search on resource change: a study of firms in lithuania

Firms in transition economies experienced a large exogenous shock in their external business environment in the late 1980s when these economies moved from a socialist‐oriented economic environment to a more market‐oriented economic environment. This paper examines the following research question in the context of this change: What are some factors that influence transition economy firms to successfully change their operating know‐how or knowledge sets to reflect the demands of their new environment? Building on some core ideas from literature on organizational imprinting, knowledge‐based view of the firm, and firm search, we suggest that two factors have a profound impact on a firm's ability to change. The imprinting effect of firms' prior socialist institutional and market environment adversely impacts their ability to change their operating knowledge. At the same time, firms that search for new knowledge from distant sources (located in mainly non‐socialist countries) are able to successfully change their knowledge to meet the demands of the new market‐oriented economy. Both of these aspects also have joint interdependent effects on the success of change; distant search mitigates some of the adverse impact of socialist market imprinting, but that is not the case for the impact of socialist institutional imprinting. These findings have interesting implications for both researchers and practitioners involved in transition economy settings. Copyright © 2006 John Wiley & Sons, Ltd.

Real-world utilization of molecular diagnostic testing and matched drug therapies in the treatment of metastatic cancers

Aims: To assess the frequency of biopsies and molecular diagnostic testing (human DNA/RNA analysis), anti-cancer drug use (genomically-matched targeted therapy [GMTT], unmatched targeted therapy [UTT], endocrine therapy [ET], and chemotherapy [CT]), and medical service costs among adults with metastatic cancer.

Methods: Adults diagnosed with metastatic breast, non-small cell lung (NSCLC), colorectal, head and neck, ovarian, and uterine cancer (2010Q1–2015Q1) were identified in the OptumHealth Care Solutions claims database and followed from first metastatic diagnosis for ≥1 month and until the end of data availability. Utilization was assessed for each cancer cohort (all and patients aged ≥65 years); per-patient-per-month (PPPM) medical service costs were assessed for all patients. Testing frequency estimates were applied to Surveillance, Epidemiology, and End Results Program data to estimate the number of untested patients (2010–2014).

Results: Patients with metastatic cancer (n?=?8,193; breast [n?=?3,414], NSCLC [n?=?2,231], colorectal [n?=?1,611], head and neck [n?=?511], ovarian [n?=?275], and uterine [n?=?151]) were 63 years old (mean), with 11.1–22.2 months of observation. Biopsy and molecular diagnostic testing frequencies ranged from 7% (uterine) to 73% (ovarian), and from 34% (head and neck) to 52% (breast), respectively. Few were treated with GMTT (breast, 11%; NSCLC, 9%; colorectal, 6%). Treatment with UTT ranged from 0.7% (uterine) to 21% (colorectal). Biopsy, diagnostic testing, and anti-cancer drug therapy were less frequent for those ≥65 years. Medical service costs (PPPM, mean) ranged from $6,618 (head and neck) to $9,940 (ovarian). The estimated number of untested new patients with metastatic cancer was 636,369 (all) and 341,397 (≥65).

Limitations: In addition to the limitations of claims analyses, diagnostic testing frequency may be under-estimated if patients underwent testing prior to study inclusion.

Conclusions: The low frequency of molecular diagnostic testing suggests there are opportunities to better inform management of patients with advanced cancer, particularly decisions to treat with GMTT.

晶化时间对CoAPO-11分子筛合成过程中转晶的影响

本文研究了晶化时间对低钴含量(x=0.1)的CoAPO-11分子筛合成过程中转晶现象的影响,并采用XRD、SEM对产物进行表征。结果表明,200℃下晶化48 h,可获得纯相CoAPO-11;当晶化时间超过48 h时,产物便开始向[Co-Al-P-O]-GIS型分子筛转化;晶化延长至72 h时,产物已全部转化为[Co-Al-P-O]-GIS型分子筛,该转化过程不可逆。从分子筛骨架结构单元出发,阐述了转晶现象的内在影响因素。
